Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, of the shaft / bearing mechanisms 40 provided on both sides in the axial direction of the movable member 30, the shaft provided on the same side as the side on which the driving force transmitting portion 52 of the actuator 50 is provided in the axial direction of the movable member 30. Since only the bearing mechanism (first shaft / bearing mechanism) 41 is composed of a torque hinge, the following actions (a) and (b) can be obtained.
(A) It is advantageous in terms of cost compared to the case where both the shaft and bearing mechanism 40 on both sides in the axial direction of the movable member 20 are constituted by torque hinges (conventional).
(B) As shown in FIGS. 4 and 5 which are comparative examples of the embodiment of the present invention, a shaft / bearing provided on the side opposite to the side where the driving force transmitting portion 52 of the actuator 50 is provided in the axial direction of the movable member 30. Compared with the case where only the mechanism (second shaft / bearing mechanism) 42 is configured by a torque hinge, the distance between the driving force transmitting portion 52 of the actuator 50 and the torque hinge can be reduced. Therefore, even in the case where only the shaft / bearing mechanism 40 on one side in the axial direction of the movable member 30 is configured by a torque hinge, the low rigidity of the casing of the movable member 30 can be smoothly rotated with respect to the fixed member 20 of the movable member 30. The influence on the movement (movement) can be suppressed.

The above action (b) will be described in detail.
As shown in FIGS. 4 and 5, which are comparative examples of the embodiment of the present invention, a shaft / bearing mechanism (first) provided on the side opposite to the side where the driving force transmitting portion 52 of the actuator 50 is provided in the axial direction of the movable member 30. When only the second shaft / bearing mechanism (42) is configured by a torque hinge, the distance between the driving force transmitting portion 52 of the actuator 50 and the torque hinge is relatively large.
Since the movable member 30 receives a force from the fixed member 20 via the driving force transmission unit 52 and the torque hinge, if the driving force transmission unit 52 and the torque hinge are separated, the movable member 30 is twisted or twisted between them. End up. As a result, for example, when the movable member 30 is in the closed position, the size of the gap with the fixed member 20 varies from side to side (on both sides in the axial direction), and the appearance is not good. For example, when the movable member 30 is moved from the closed position to the open position, even if the actuator 50 starts to operate, the movable member 30 does not move due to the twist or twist of the movable member 30 (smooth operation does not occur).
However, in the embodiment of the present invention, only the shaft / bearing mechanism (first shaft / bearing mechanism) 41 provided on the same side as the side where the driving force transmission portion 52 of the actuator 50 is provided in the axial direction of the movable member 30 is torqued. Since it is configured with a hinge, the distance between the driving force transmission portion 52 of the actuator 50 and the torque hinge can be significantly reduced as compared with the comparative example of the present invention. Therefore, compared to the case of the comparative example of the present invention, it is possible to significantly suppress the rigidity of the casing of the movable member 30 from affecting the appearance and smooth rotation (movement) of the movable member 30.

In the embodiment of the present invention, the following action can be further obtained.
(A) Since the constituent material of the torque hinge constituting the first shaft / bearing mechanism 41 is a metal material, a resin member such as rubber is unnecessary, which is advantageous in terms of wear resistance. Therefore, it is advantageous in terms of durability of the apparatus 10 as compared with a case where a resin member such as rubber is required.
(B) Since the torque hinge constituting the first shaft / bearing mechanism 41 includes the wave washer 41b, components other than the plate A41d of the first shaft / bearing mechanism 41 are in the axial direction with respect to the plate A41d. The rattling is suppressed. Therefore, the movable member 30 is prevented from rattling in the axial direction with respect to the fixed member 20.
(C) Since the constituent material of the torque hinge constituting the first shaft / bearing mechanism 41 is a metal material, the radial clearance between the constituent members can be set to the minimum gap targeted by the design relatively easily. it can. Therefore, it is possible to prevent the constituent members other than the plate A41d of the first shaft / bearing mechanism 41 from rattling in the radial direction with respect to the plate A41d. Therefore, the movable member 30 is prevented from rattling with respect to the fixed member 20 in the radial direction.
(D) Since the torque hinge constituting the first shaft / bearing mechanism 41 applies a braking force to the rotation of the movable member 30 relative to the fixed member 20, the gears included in the actuator 50 are engaged with each other by the amount of backlash. Inversion is suppressed. Therefore, it is possible to suppress the occurrence of abnormal noise in the gears (a hitting sound that occurs when the meshing gears hit each other).
